When Do You Use unconscionable?

Something that can't be done in good conscience is unconscionable, and such acts can range from betraying a confidence to mass murder. For a five-syllable word, unconscionable is actually quite common. This is partly because it isn't always used very seriously; so, for example, a critic is free to call a fat new book "an unconscionable waste of trees". In law, an unconscionable contract is one that, even though it was signed by both parties, is so ridiculous that a judge will just throw it out.
